FRANC – Subsoiler


FRANC subsoiler is used for deep chisel tillage, leaving on the surface 30-60% of crop residues, which solves the problem of soil erosion, maintaining the organic composition of the soil and ensuring its long-term fertility.

Duration of the agronomic effect is 3-4 years, and the number of active roots in subsoiled area is doubled.

FRANC is one of the most effective means to improve water-air soil regimes, capable to create quality mulch from the crop residues. It is designed for loosening of the soil compacted by the horizontal cultivation implements, such as plows, disc and tine cultivators


FRANC is conceptually similar to the most common European subsoilers.

Frank.jpg — Working tools

Quick-change front point and shim protect the tine from wear, and the geometric configuration allows deeper penetration of the working tool into firm soil.

Durable straight tine chisels soil at right angle without moving soil aside, and requires smaller draft compared to “paraplau” tines.

Frank_3.jpg — Wings effect, “soil wave blasting”

Side wings, fixed with bolts on the tine, increase subsoiling effect. Application of the side wings at high speed causes the “firm soil wave blasting” effect.

Balance mounting of the doubled roller provides the constant contact of both rollers with the soil. Central screw allows to adjust roller relatively to linear plane.

Frank_1.jpg — Advantages of self-cleaning roller with spikes

Subsoiler is equipped with doubled crowfoot roller for additional topsoil crushing and leveling of the field surface, and even distribution of crop residues. Spikes break large clods, thrown on the surface, prepare and level the soil, facilitating further final seedbed preparation. Rotating spikes embed crop residues into the lower layers of soil and mix them with soil at depth of 15-20 cm.

Frank_2.jpg — Frame protection against overloading

Shear bolt is applied for protection against exceeding loads, excluding the possible damage to frame

Frank_5.jpg — Simple depth adjustment

Working depth is adjusted by pins on the roller mounting parallelogram for the front tines and on the rear tines mounting parallelogram.

FRANC-3sp is equipped with mechanical combined compression spring and separation bolt to prevent damage of frame.

DSC_0004.JPG — Premium class bearing unit

FRANC is assembled with superreliable maintenance-free HARP AGRO UNIT bearing units. Application of high-quality German plain bearings prevents wear of the roller adjustment mechanism rotary units.

Gulden_5.jpg — Different tillage ways by roller adjustment

Depending on the tillage purposes, rollers can be set for uniform work, or only front/rear roller can be accented. For this purpose the roller draught shall be adjusted.

Frank_7.jpg — Simple maintenance

Bolts allow to change worn or damaged part quickly.


granulated fertilizers deep application system

Optionally, the subsoiler can be equipped with the fertilizers deep application system HF Agro. This system enables application of granulated fertilizers during soil tillage. 

Depth of application can be changed (150 mm or 250 mm).

Available two types of the application mechanism drive: mechanical - from drive wheel, or electrical - from electric drive.
